In items->attachments is an array of objects. Each of the objects has a type field, which has a value, for example, audio or photo, depending on the type. This value uniquely determines the type and, accordingly, the required tag. No problems either.

if the photo array exists - display its contents in a loop, say with photo_75
if the audio array exists - display the contents of the url
